"At the time of Ulysses S. Grant's election to the presidency, white supremacists were conducting a reign of terror throughout the South. In outright defiance of the Republican-led federal government, Southern Democrats formed organizations that violently intimidated blacks and Republicans who tried to win political power.
The most prominent of these, the Ku Klux Klan, was formed in Pulaski, Tennessee, in 1865. Originally founded as a social club for former Confederate soldiers, the Klan evolved into a terrorist organization. It would be responsible for thousands of deaths, and would help to weaken the political power of Southern blacks and Republicans.
Racist activity in the South often took the form of riots that targeted blacks and Republicans. In 1866, a quarrel between whites and black ex-soldiers erupted into a full-fledged riot in Memphis, Tennessee. White policemen assisted the mobs in their violent rampage through the black sections of town. By the time the violence ended, 46 people were dead, 70 more were wounded, and numerous churches and schools had been burned. Just two months later, on July 30, a similar outbreak of violence erupted in New Orleans. This time, a white mob attacked the attendees of a black suffrage convention, killing 37 blacks and 3 whites who allied with them.
In this violent atmosphere, the Ku Klux Klan grew in size and strength. By 1868, the Klan had evolved into a hooded terrorist organization that its members called "The Invisible Empire of the South." The reorganized Klan's first leader, or "Grand Wizard," was Nathan Bedford Forrest, who had been a Confederate general during the Civil War."
